smu_v15_0_set_single_dpm_table() queries fine-grained DPM status and
per-level frequencies from SMU; when DPM is disabled both callees
smu_v15_0_get_fine_grained_status() and
smu_v15_0_get_dpm_freq_by_index() return 0 without writing their output
arguments, leaving is_fine_grained and clk uninitialized before use.
Initialize both to zero to reflect the correct no-op semantics when DPM
is disabled.
